All accelerometer data has been reprocessed to ensure consistency across waves.

Compared to the first release, the updated ICAD includes more longitudinal data and provides access to a wider range of non-accelerometer data. provide a means to study the causes of inter-study variability in physical activity.Д®arly 2017, a new version of ICAD was released.standardize and optimize the analytical methods used in the generation of outcome variables, and.create a more heterogeneous and potentially more representative sample.increase statistical power due to a large sample size.In addition, non-accelerometer data were harmonised in a transparent and structured way.Д«y pooling data from different studies the ICAD has the potential to: Data were processed to create comparable accelerometer variables in over 37,000 young people aged 3 to 18 years across studies from Europe, the US, Brazil and Australia. The International ChildrenвЂ™s Accelerometry Database (ICAD) project is a consortium including 20 partners which pooled and reduced raw accelerometer data using standardized methods. Objective methods, such as accelerometers, have become a preferred option when measuring population levels of physical activity, examining trends in activity patterns and when examining associations between activity and health outcomes in young people.
